6.1.3

DE-EMPHASIS CONTROL (DEM) BIT 2-3

Default = 00

00 - Disabled

01 - 44.1 kHz

10 - 48 kHz

11 - 32 kHz

Function:

Selects the appropriate digital filter to maintain the standard 15

µs/50 µs digital de-emphasis filter re-

sponse at 32-, 44.1- or 48-kHz sample rates. (See Figure 18.)

Note:

De-emphasis is only available in Single-speed Mode.

FUNCTIONAL MODE (FM) BIT 0-1

Default = 00

00 - Single-speed Mode (4- to 50-kHz sample rates)

01 - Double-speed Mode (50- to 100-kHz sample rates)

10 - Quad-speed Mode (100- to 200-kHz sample rates)

11 - Reserved

Function:

Selects the required range of input sample rates.

6.2

INVERT SIGNAL (ADDRESS 02H)

6.2.1

INVERT SIGNAL POLARITY (INV_XX) BIT 0-5

Default = 0

0 - Disabled

1 - Enabled

Function:

When enabled, these bits invert the signal polarity for each of their respective channels.
